Practice Questions for Respiratory System Questions
Question 1 of 5
Which vertebrate body system is most closely associated functionally with respiration?
Correct Answer: D
Rationale: The correct answer is D: circulatory system. This system is most closely associated with respiration as it transports oxygen from the lungs to the body's tissues and removes carbon dioxide. The circulatory system includes the heart, blood vessels, and blood. The other choices (A: urinary, B: digestive, C: endocrine) are not directly involved in the process of respiration and do not play a significant role in the exchange of gases in the body.
Question 2 of 5
Asphyxia occurs due to
Correct Answer: A
Rationale: The correct answer is A: Rise in level of CO2. Asphyxia occurs when there is a buildup of carbon dioxide (CO2) in the body, leading to a lack of oxygen supply to tissues. When CO2 levels rise, it can displace oxygen in the bloodstream, causing respiratory distress and potential suffocation. Choices B, C, and D are incorrect because a fall in CO2 levels, a rise in O2 levels, or a fall in O2 levels do not directly cause asphyxia. This highlights the importance of understanding the physiological processes involved in respiration to identify the correct answer.
Question 3 of 5
The function of tracheal cilia is to
Correct Answer: A
Rationale: The correct answer is A: Pass mucus out. Tracheal cilia help move mucus, which contains dust, debris, and pathogens, out of the respiratory tract to prevent infections and maintain clear airways. This process is known as mucociliary clearance. Choices B, C, and D are incorrect because tracheal cilia do not pass mucus in, pass air out, or pass air in. Tracheal cilia specifically function to clear mucus out of the respiratory tract.
Question 4 of 5
A nurse observes that a client's anteroposterior (AP) chest diameter is the same as the lateral chest diameter. Which question would the nurse ask the client in response to this finding?
Correct Answer: B
Rationale: The correct answer is B: Do you have any chronic breathing problems? This question is appropriate because equal AP and lateral chest diameters could indicate barrel chest, which is often associated with chronic obstructive pulmonary disease (COPD) or other chronic breathing problems. Asking about chronic breathing problems can help the nurse further assess the client's respiratory health. Incorrect answers: A: Are you taking any medications or herbal supplements? This question is not directly related to the observed chest diameter findings. C: How often do you perform aerobic exercise? This question is not relevant to the physical assessment findings and does not address the potential respiratory issue. D: What is your occupation and what are your hobbies? This question does not directly address the equal AP and lateral chest diameters and does not help in assessing the respiratory status of the client.
Question 5 of 5
A nurse is planning discharge teaching on tracheostomy care for an older client. What factors does the nurse need NOT to assess before teaching this particular client?
Correct Answer: C
Rationale: The correct answer is C. Hydration is not directly related to tracheostomy care. The rationale is: A) Cognition is important for understanding and following care instructions. B) Dexterity is needed for handling tracheostomy equipment. C) Hydration, while important for overall health, does not directly impact tracheostomy care. D) Range of motion is relevant to prevent complications like skin breakdown. In summary, hydration is not a crucial factor to assess specifically for tracheostomy care compared to cognition, dexterity, and range of motion.
